γ‐Modification of poly[(N,N‐diethyl­dithio­carbamato)silver(I)]

In the title compound, catena‐polytri­silver(I)‐tri‐μ₃‐N,N‐diethyl­dithio­carbamato‐3′κS:1κS′:2κS;1κS:2κS′:3κS;2κS:3κ²S,S′:1′κS′], Ag₃(C₅H₁₀NS₂)₃]_n, the trigonally and tetra­hedrally coordinated Ag atoms are μ₃‐bridged by κ³‐ and κ⁴‐S₂CNEt₂ ligands to form a ribbon structure along the c axis. There is a twofold axis parallel to the b axis and passing through the tetra­hedrally coordinated Ag atom. The S₂CNEt₂ ligands coordinate the Ag atoms in η¹,η²‐ and η²,η²‐fashions, depending on the bridging S atoms. The distances between the trigonal Ag and S atoms are 2.4915 (11)–2.6205 (11) Å, while those between the tetra­hedral Ag and S atoms are 2.5457 (11) and 2.7145 (10) Å. The shortest Ag?Ag distance between trigonal Ag atoms is 2.8336 (7) Å, which indicates a weak Ag?Ag inter­action, whereas the shortest distance between trigonal and tetra­hedral Ag atoms is 3.463 (6) Å, which is considered as non‐bonding.
